利用浸渍法将Fe2(SO4)3溶液负载到β分子筛上,经过焙烧制得β分子筛负载SO42-/Fe2O3固体超强酸催化剂.并以乙酸丁酯的酯化反应为探针,考查了β分子筛与Fe2(SO4)3的质量比、焙烧时间、焙烧温度对催化剂酯化性能的影响,得到了较佳的制备条件:Fe与β分子筛质量比为5∶2,焙烧温度550℃,焙烧时间4 h.用指示剂法测其酸强度H0≤12.7,为固体超强酸. The Fe2 (SO4) 3 solution was impregnated onto the β molecular sieve by impregnation method and then calcined to obtain the zeolite SO42- / Fe2O3 solid superacid catalyst, and the esterification reaction of butyl acetate was used as the probe, Fe2 (SO4) 3 mass ratio, calcination time and calcination temperature on the esterification performance were studied. The optimum preparation conditions were as follows: mass ratio of Fe to β zeolite 5: 2, calcination temperature 550 ℃, calcination time 4 h Using the indicator method to measure the acid strength H0 ≤ 12.7, as solid superacid.
